Some of us tend to create url's directly from the link we get from the main website, and SEF is really helpful in making our links much more readable. Though, sometimes, we tend to get the SEF'd url and when we edit the article, we tend to break the link. Here's a quick tip on creating URL's that doesn't need that much maintenance.

• Before editing or creating an article that have links on it (unless its really an external link), try to disable the SEF for a while
• Paste or enter the internal url in this format "index.php?article_link_here " (or the internal non sef'd article link)
